Heat the olive oil in a large skillet over medium heat. Add the ground beef and break into chunks with a wooden spoon. Cook for 3-4 minutes until about halfway cooked, then add the onion. Cook for another 5 minutes until the onion has softened, then stir in the garlic, smoked paprika and red pepper flakes and cook 30 seconds longer.

Add the cabbage and stir well. Cook for about 5-6 minutes until browned and somewhat softened (it will be crisp tender at this point). Add the diced tomatoes, tomato sauce, vinegar and oregano and stir to combine. Simmer on medium low for 10 -15 minutes until the sauce has thickened and the cabbage is cooked to the desired doneness. Taste and season with salt and pepper as needed.

Remove from heat and sprinkle the grated cheese over the top and cover until the cheese has melted. Serve and enjoy!
